PNEUMATIC STRAW-STACKER.

SPECIFICATION forming part of Letters Patent No. 609,623, dated August23, 1898. Application filed June 5, 1897- Serial No. 639,547. (Nomodel.)

To aZZ whom, it may concern.-

Beit known that I, JoHNB. MoOUToHEoN, a citizen of the United States,residing at Battle Creek, in the county of Calhoun and State ofMichigan, have invented certain new and useful Improvements in PneumaticStraw-Stackers, of which the following is a specification.

The object of my said invention is to improve that variety of pneumaticstraw-stackers which are provided with telescoping trunks or chuteswhich are capable of being extended or contracted as desired.

Said invention consists in certain improvements of the construction andarrangement of parts, all as will be hereinafter more particularlydescribed and claimed.

Referring to the accompanying drawings, which are made a part hereof,and on which similar letters of reference indicate similar parts, Figure1 is a view, partly in central vertical section and partly in sideelevation,of the trunk or chute of a pneumatic straw-stacker embodyingmy said invention, the same being mounted upon the usual turn-table;Figs. 2, 3, and at, transverse sectional views of the same on the dottedlines 2 2, 3 3, and i 4:, respectively Fig. 5, a transverse sectionalview as seen from the dotted line 5 5 in Fig. 1,

showing the yoke-frame and the gear mounted thereon in elevation; andFig. 6 a detail sectional view showing the spring attachment to whichone end of the rope by which the telescoping operation is effected isattached.

In said drawings the portions marked A represent the turn-table of apneumatic strawstacker; B,the pivoted yoke or frame by which the movableportion of the stacker-chute is carried; C C C the several sections of apneumatic stacker trunk or chute; D, the rope by which the telescopingsection C is moved; E, a hood or mouthpiece on the end of the stacker;F, the rope by which said hood or mouthpiece may be manipulated, and G atackle by which the trunk or chute of the stacker as a whole is elevatedor depressed.

The trunk or chute, as is usual in telescopic devices of this character,is composed mainly of the sections C and C the latter of which issomewhat larger in diameter than and surrounds the former. Within thesection C is secured a hollow rib c, which forms a tubular passage forone strand of the rope D. At the forward end of this hollow rib isplaced a sheave d, over which said rope passes. The outer-section Cslides over the inner section C and is preferably provided with a springattaching device C for the other end of the rope D. The springcharacterof the attachment is so that the rope shall always be held at aproper tension. It consists, as shown, of a rod 0 having an ad justing-nut c on its end, and a spring 8, surrounding said rod andinterposed between said nut and a stationary ring C on the part C saidring also forming a support and bearing for the rod 0 There is alsopreferably provided on the lower side at the inner end of said section Can antifriction-truck 0 which runs on a track t on the under side of thesection 0.

The rope D runs from the rod C of the springiattaching device over apulley b on the upper end of the yoke or frame B, and thence around aspool Z), mounted on a shaft B on said frame, thence into the passageformed by the hollow rib 0', around the sheave d, and back between thetrunk parts C and C to the inner end of said trunk part C to which it isfastened at the point p. Said sheave d is shown as arranged in avertical position in respect to the trunk or chute, and I prefer thisarrangement, as thus the ropes are kept in line. In operation windingthe shaft B by means of the crank B 01 otherwise will wind the rope D inthe desired direction, and the stacker-trunk part C will thereby beextended or withdrawn, as the case may be.

The hood or mouthpiece E is carried by a rock-shaft E, mounted-at theextreme forward end of the trunk part C An arm 8 on said shaft isconnected to the rope F, and

said rope F runs back to a spool 19 on the tion, what I claim as new,and desire to secure by Letters Patent, is

1. The combination, in a pneumatic strawstacker, of the telescopic parts0 and 0 an interior hollow rib 0, within said part '0', avertically-positioned sheave 01 mounted at the front end thereof, a ropeD passing from the inner end of the outer part (3" between the two partsto the outer end of said inner part, and over the sheave d, thence backthrough said hollow rib, out through -a perforation in said part 0,around suitable spools, and thence to an attachment on the outer portionof said trunk part 0 said several parts be ing arranged and operatingsubstantially as shown and described.

2. The combination, in a telescopic trunk or chute for pneumaticstackers, of two parts or sections, the inner section having aperforation in the upper side thereof, a hollow interior rib thereinleading forward from said perforation, a sheave mounted therein at theforward end of said rib, and a rope passing within said hollow ribaround said sheave and thence between the two parts or sections to theinner or lower end of the outer part or section, to which it isconnected, substantially as shown and described.

In witness whereof I have hereunto set my hand and seal, at BattleCreek, Michigan, this 1st day of June, A. D. 1897.

JOHN B. McoUTcHEoN.
